茉莉花单元测试 - 测试对象的未定义属性 [英] jasmine unit testing - testing for an undefined property of an object

问题描述

我有以下声明

expect(A.["BAR"].name).toEqual("foo"); 

由于我的对象A具有顶级属性BAR而bar具有值foo传递。

which due to the fact my object A has the top level property "BAR" and bar has the value "foo" passes.

我想测试我的结构以确认属性NONEXISTINGPROP尚未定义。
例如。

I'd like to test my structure to confirm a property "NONEXISTINGPROP" has not be defined. e.g.

expect(A.["NONEXISTINGPROP"].name).not.toBeDefined(); 

但我似乎得到了

  "TypeError: A.[NONEXISTINGPROP] is undefined" 

茉莉花测试跑步者这正是我想要确认的。知道为什么Jasmine在哭。我希望它能通过这个。

in the jasmine test runner this is exactly what I want to confirm. Any idea why Jasmine is crying. I was hoping for it to pass this.

谢谢SO
